FIELD OF THE INVENTION

The invention relates generally to compounds with anti-cancer activityand more specifically to compounds which inhibit PI3 kinase activity.The invention also relates to methods of using the compounds for invitro, in situ, and in vivo diagnosis or treatment of mammalian cells,or associated pathological conditions.

BACKGROUND OF THE INVENTION

Phosphatidylinositol (hereinafter abbreviated as “PI”) is one of anumber of phospholipids found in cell membranes. In recent years it hasbecome clear that PI plays an important role in intracellular signaltransduction. Cell signaling via 3′-phosphorylated phosphoinositides hasbeen implicated in a variety of cellular processes, e.g., malignanttransformation, growth factor signaling, inflammation, and immunity(Rameh et al (1999) J. Biol Chem, 274:8347-8350). The enzyme responsiblefor generating these phosphorylated signaling products,phosphatidylinositol 3-kinase (also referred to as PI 3-kinase or PI3K),was originally identified as an activity associated with viraloncoproteins and growth factor receptor tyrosine kinases thatphosphorylate phosphatidylinositol (PI) and its phosphorylatedderivatives at the 3′-hydroxyl of the inositol ring (Panayotou et al(1992) Trends Cell Biol 2:358-60).

Phosphoinositide 3-kinases (PI3K) are lipid kinases that phosphorylatelipids at the 3-hydroxyl residue of an inositol ring (Whitman et al(1988) Nature, 332:664). The 3-phosphorylated phospholipids (PIP3s)generated by PI3-kinases act as second messengers recruiting kinaseswith lipid binding domains (including plekstrin homology (PH) regions),such as Akt and phosphoinositide-dependent kinase-1 (PDK1). Binding ofAkt to membrane PIP3s causes the translocation of Akt to the plasmamembrane, bringing Akt into contact with PDK1, which is responsible foractivating Akt. The tumor-suppressor phosphatase, PTEN, dephosphorylatesPIP3 and therefore acts as a negative regulator of Akt activation. ThePI3-kinases Akt and PDK1 are important in the regulation of manycellular processes including cell cycle regulation, proliferation,survival, apoptosis and motility and are significant components of themolecular mechanisms of diseases such as cancer, diabetes and immuneinflammation (Vivanco et al (2002) Nature Rev. Cancer 2:489; Phillips etal (1998) Cancer 83:41).

The PI3 kinase family comprises at least 15 different enzymessub-classified by structural homology and are divided into 3 classesbased on sequence homology and the product formed by enzyme catalysis.The class I PI3 kinases are composed of 2 subunits: a 110 kd catalyticsubunit and an 85 kd regulatory subunit. The regulatory subunits containSH2 domains and bind to tyrosine residues phosphorylated by growthfactor receptors with a tyrosine kinase activity or oncogene products,thereby inducing the PI3K activity of the p110 catalytic subunit whichphosphorylates its lipid substrate. Class I PI3 kinases are involved inimportant signal transduction events downstream of cytokines, integrins,growth factors and immunoreceptors, which suggests that control of thispathway may lead to important therapeutic effects such as modulatingcell proliferation and carcinogenesis. Class I PI3Ks can phosphorylatephosphatidylinositol (PI), phosphatidylinositol-4-phosphate, andphosphatidylinositol-4,5-biphosphate (PIP2) to producephosphatidylinositol-3-phosphate (PIP),phosphatidylinositol-3,4-biphosphate, andphosphatidylinositol-3,4,5-triphosphate, respectively. Class II PI3Ksphosphorylate PI and phosphatidylinositol-4-phosphate. Class III PI3Kscan only phosphorylate PI.

The main PI3-kinase isoform in cancer is the Class I PI3-kinase, p110α.(U.S. Pat. No. 5,824,492; U.S. Pat. No. 5,846,824; U.S. Pat. No.6,274,327). Other isoforms are implicated in cardiovascular andimmune-inflammatory disease (Workman P (2004) “Inhibiting thephosphoinositide 3-kinase pathway for cancer treatment” Biochem SocTrans 32:393-396; Patel et al (2004) “Identification of potent selectiveinhibitors of PI3K as candidate anticancer drugs” Proceedings of theAmerican Association of Cancer Research (Abstract LB-247) 95th AnnualMeeting, March 27-31, Orlando, Fla., USA; Ahmadi K and Waterfield M D(2004) “Phosphoinositide 3-Kinase: Function and Mechanisms” Encyclopediaof Biological Chemistry (Lennarz W J, Lane M D eds) Elsevier/AcademicPress).

Several components of the PI3-kinase/Akt/PTEN pathway are implicated inoncogenesis. In addition to growth factor receptor tyrosine kinases,integrin-dependent cell adhesion and G-protein coupled receptorsactivate PI3-kinase both directly and indirectly through adaptormolecules. Functional loss of PTEN (the most commonly mutatedtumor-suppressor gene in cancer after p53), oncogene mutations in PI3kinase (Samuels et al (2004) Science 304:554), amplification ofPI3-kinase and overexpression of Akt have been established in manymalignancies. In addition, persistent signaling through thePI3-kinase/Akt pathway by stimulation of the insulin-like growth factorreceptor is a mechanism of resistance to epidermal growth factorreceptor inhibitors such as AG1478 and trastuzumab. Oncogenic mutationsof p110alpha have been found at a significant frequency in colon,breast, brain, liver, ovarian, gastric, lung, and head and neck solidtumors. PTEN abnormalities are found in glioblastoma, melanoma,prostate, endometrial, ovarian, breast, lung, head and neck,hepatocellular, and thyroid cancers.

The levels of phosphatidylinositol-3,4,5-triphosphate (PIP3), theprimary product of PI3-kinase activation, increase upon treatment ofcells with a variety of agonists. PI3-kinase activation, therefore, isbelieved to be involved in a range of cellular responses including cellgrowth, differentiation, and apoptosis (Parker et al (1995) CurrentBiology, 5:577-99; Yao et al (1995) Science, 267:2003-05). Though thedownstream targets of phosphorylated lipids generated following PI3kinase activation have not been well characterized, emerging evidencesuggests that pleckstrin-homology domain- and FYVE-fingerdomain-containing proteins are activated when binding to variousphosphatidylinositol lipids (Sternmark et al (1999) J Cell Sci,112:4175-83; Lemmon et al (1997) Trends Cell Biol, 7:237-42). In vitro,some isoforms of protein kinase C (PKC) are directly activated by PIP3,and the PKC-related protein kinase, PKB, has been shown to be activatedby PI3 kinase (Burgering et al (1995) Nature, 376:599-602).

The initial purification and molecular cloning of PI3 kinase revealedthat it was a heterodimer consisting of p85 and p110 subunits (Otsu etal (1991) Cell 65:91-104; Hiles et al (1992) Cell 70:419-29). Sincethen, four distinct Class I PI3Ks have been identified, designated PI3Kα (alpha), β (beta), δ (delta), and ω (gamma), each consisting of adistinct 110 kDa catalytic subunit and a regulatory subunit. Morespecifically, three of the catalytic subunits, i.e., p110.alpha.,p110.beta. and p110.delta., each interact with the same regulatorysubunit, p85; whereas p110.gamma. interacts with a distinct regulatorysubunit, p101. As described below, the patterns of expression of each ofthese PI3Ks in human cells and tissues are also distinct.

The cellular functions of the individual isoforms of PI3 kinases are notcompletely elucidated. Bovine p110 alpha was described after cloning asrelated to the Saccharomyces cerevisiae protein: Vps34p, a proteininvolved in vacuolar protein processing. The recombinant p110 alphaproduct was also shown to associate with p85 alpha, to yield a PI3Kactivity in transfected COS-1 cells (Hiles et al. (1992), Cell,70:419-29). A second human p110 isoform was cloned and designated p110beta (Hu et al (1993) Mol Cell Biol 13:7677-88). This isoform is said toassociate with p85 in cells, and to be ubiquitously expressed, as p110beta mRNA has been found in numerous human and mouse tissues as well asin human umbilical vein endothelial cells, Jurkat human leukemic Tcells, 293 human embryonic kidney cells, mouse 3T3 fibroblasts, HeLacells, and NBT2 rat bladder carcinoma cells. Identification of the p110delta isoform of PI3 kinase is described in Chantry et al., J Biol Chem,272:19236-41 (1997). It was observed that the human p110 delta isoformis expressed in a tissue-restricted fashion. It is expressed at highlevels in lymphocytes and lymphoid tissues, suggesting that the proteinmight play a role in PI3 kinase-mediated signaling in the immune system(U.S. Pat. No. 5,858,753; U.S. Pat. No. 5,822,910; U.S. Pat. No.5,985,589; WO 97/46688; and Vanhaesebroeck et al (1997) Proc Natl AcadSci USA, 94:4330-5).

In each of the PI3K alpha, beta, and delta subtypes, the p85 subunitacts to localize PI3 kinase to the plasma membrane by the interaction ofits SH2 domain with phosphorylated tyrosine residues (present in anappropriate sequence context) in target proteins (Rameh et al (1995)Cell, 83:821-30). Two isoforms of p85 have been identified, p85alpha,which is ubiquitously expressed, and p85 beta, which is primarily foundin the brain and lymphoid tissues (Volinia et al (1992) Oncogene,7:789-93). Association of the p85 subunit to the PI3 kinase p110 alpha,beta, or delta catalytic subunits appears to be required for thecatalytic activity and stability of these enzymes. In addition, thebinding of Ras proteins also upregulates PI3 kinase activity. Cloning ofp110 gamma revealed further complexity within the PI3K family of enzymes(Stoyanov et al (1995) Science, 269:690-93). The p110 gamma isoform isclosely related to p110 alpha and p110 beta (45-48% identity in thecatalytic domain), but does not make use of p85 as a targeting subunit.Instead, PI3K contains an additional domain termed a “pleckstrinhomology domain” near its amino terminus. This domain allows interactionof p110 gamma with the beta, gamma subunits of heterotrimeric G proteinsand this interaction appears to regulate its activity. The p101regulatory subunit for PI3Kgamma was originally cloned in swine, and thehuman ortholog identified subsequently (Krugmann et al (1999) J BiolChem, 274:17152-8).

Thus, PI3 kinases can be defined by their amino acid identity or bytheir activity. Additional members of this growing gene family includemore distantly related lipid and protein kinases including Vps34 TOR1,and TOR2 of Saccharomyces cerevisiae (and their mammalian homologs suchas FRAP and mTOR), the ataxia telangiectasia gene product (ATR) and thecatalytic subunit of DNA-dependent protein kinase (DNA-PK). Seegenerally, Hunter (1995) Cell, 83:1-4.

PI3 kinase also appears involved in leukocyte activation. Ap85-associated PI3 kinase activity has been shown to physicallyassociate with the cytoplasmic domain of CD28, which is an importantcostimulatory molecule for the activation of T-cells in response toantigen (Pages et al (1994) Nature, 369:327-29; Rudd, (1996) Immunity4:527-34). Activation of T cells through CD28 lowers the threshold foractivation by antigen and increases the magnitude and duration of theproliferative response. These effects are linked to increases in thetranscription of a number of genes including interleukin-2 (IL2), animportant T cell growth factor (Fraser et al (1991) Science,251:313-16). Mutation of CD28 such that it can no longer interact withPI3 kinase leads to a failure to initiate IL2 production, suggesting acritical role for PI3 kinase in T cell activation.

Inhibition of class I PI3 kinase induces apoptosis, blocks tumor inducedangiogenesis in vivo, and increases the radiosensitivity of certaintumors. At least two compounds, LY294002 and wortmannin, have beenwidely used as PI3 kinase inhibitors. These compounds, however, arenonspecific PI3K inhibitors, as they do not distinguish among the fourmembers of Class I PI3 kinases. For example, the IC50 values ofwortmannin (U.S. Pat. No. 6,703,414) against each of the various Class IPI3 kinases are in the range of 1-10 nanomolar (nM). LY294002(2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one) is a well knownspecific inhibitor of class I PI3 kinases and has anti-cancer properties(Chiosis et al (2001) Bioorganic & Med. Chem. Lett. 11:909-913; Vlahoset al (1994) J. Biol. Chem. 269(7):5241-5248; Walker et al (2000) Mol.Cell 6:909-919; Fruman et al (1998) Ann Rev Biochem, 67:481-507).However, the anti-cancer applications of LY294002 are severely limitedby its lack of aqueous solubility and its poor pharmacokinetics.Moreover, LY294002 has no tissue specific properties and has beendemonstrated to be rapidly metabolized in animals. Because of thesefactors, LY294002 would need to be administered at frequent intervalsand thus has the potential to also inhibit PI3 kinases in normal cellsthereby leading to undesirable side effects.

There continues to be a need for class I PI3 kinase inhibitors withimproved pharmacokinetic and pharmacodynamic properties. The PI3kinase/Akt/PTEN pathway is thus an attractive target for cancer drugdevelopment since such agents would be expected to inhibitproliferation, reverse the repression of apoptosis and surmountresistance to cytotoxic agents in cancer cells. PI3 kinase inhibitorshave been reported (Yaguchi et al (2006) Jour. of the Nat. Cancer Inst.98(8):545-556; U.S. Pat. No. 6,608,056; U.S. Pat. No. 6,608,053; U.S.Pat. No. 6,838,457; U.S. Pat. No. 6,770,641; U.S. Pat. No. 6,653,320;U.S. Pat. No. 6,403,588; WO 2004017950; US 2004092561; WO 2004007491; WO2004006916; WO 2003037886; US 2003149074; WO 2003035618; WO 2003034997;US 2003158212; EP 1417976; US 2004053946; JP 2001247477; JP 08175990; JP08176070). Wortmannin analogs have PI3 kinase activity in mammals (U.S.Pat. No. 6,703,414; WO 97/15658).

The term “chiral” refers to molecules which have the property ofnon-superimposability of the mirror image partner, while the term“achiral” refers to molecules which are superimposable on their mirrorimage partner.

The term “stereoisomers” refers to compounds which have identicalchemical constitution, but differ with regard to the arrangement of theatoms or groups in space.

“Diastereomer” refers to a stereoisomer with two or more centers ofchirality and whose molecules are not mirror images of one another.Diastereomers have different physical properties, e.g. melting points,boiling points, spectral properties, and reactivities. Mixtures ofdiastereomers may separate under high resolution analytical proceduressuch as electrophoresis and chromatography.

“Enantiomers” refer to two stereoisomers of a compound which arenon-superimposable mirror images of one another.

Stereochemical definitions and conventions used herein generally followS. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984)McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S.,“Stereochemistry of Organic Compounds”, John Wiley & Sons, Inc., NewYork, 1994. The compounds of the invention may contain asymmetric orchiral centers, and therefore exist in different stereoisomeric forms.It is intended that all stereoisomeric forms of the compounds of theinvention, including but not limited to, diastereomers, enantiomers andatropisomers, as well as mixtures thereof such as racemic mixtures, formpart of the present invention. Many organic compounds exist in opticallyactive forms, i.e., they have the ability to rotate the plane ofplane-polarized light. In describing an optically active compound, theprefixes D and L, or R and S, are used to denote the absoluteconfiguration of the molecule about its chiral center(s). The prefixes dand l or (+) and (−) are employed to designate the sign of rotation ofplane-polarized light by the compound, with (−) or 1 meaning that thecompound is levorotatory. A compound prefixed with (+) or d isdextrorotatory. For a given chemical structure, these stereoisomers areidentical except that they are mirror images of one another. A specificstereoisomer may also be referred to as an enantiomer, and a mixture ofsuch isomers is often called an enantiomeric mixture. A 50:50 mixture ofenantiomers is referred to as a racemic mixture or a racemate, which mayoccur where there has been no stereoselection or stereospecificity in achemical reaction or process. The terms “racemic mixture” and “racemate”refer to an equimolar mixture of two enantiomeric species, devoid ofoptical activity.

The term “tautomer” or “tautomeric form” refers to structural isomers ofdifferent energies which are interconvertible via a low energy barrier.For example, proton tautomers (also known as prototropic tautomers)include interconversions via migration of a proton, such as keto-enoland imine-enamine isomerizations. Valence tautomers includeinterconversions by reorganization of some of the bonding electrons.

The phrase “pharmaceutically acceptable salt” as used herein, refers topharmaceutically acceptable organic or inorganic salts of a compound ofthe invention. Exemplary salts include, but are not limited, to sulfate,citrate, acetate, oxalate, chloride, bromide, iodide, nitrate,bisulfate, phosphate, acid phosphate, isonicotinate, lactate,salicylate, acid citrate, tartrate, oleate, tannate, pantothenate,bitartrate, ascorbate, succinate, maleate, gentisinate, fumarate,gluconate, glucuronate, saccharate, formate, benzoate, glutamate,methanesulfonate “mesylate”, ethanesulfonate, benzenesulfonate,p-toluenesulfonate, and pamoate (i.e.,1,1′-methylene-bis-(2-hydroxy-3-naphthoate)) salts. A pharmaceuticallyacceptable salt may involve the inclusion of another molecule such as anacetate ion, a succinate ion or other counter ion. The counter ion maybe any organic or inorganic moiety that stabilizes the charge on theparent compound. Furthermore, a pharmaceutically acceptable salt mayhave more than one charged atom in its structure. Instances wheremultiple charged atoms are part of the pharmaceutically acceptable saltcan have multiple counter ions. Hence, a pharmaceutically acceptablesalt can have one or more charged atoms and/or one or more counter ion.

If the compound of the invention is a base, the desired pharmaceuticallyacceptable salt may be prepared by any suitable method available in theart, for example, treatment of the free base with an inorganic acid,such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid,methanesulfonic acid, phosphoric acid and the like, or with an organicacid, such as acetic acid, maleic acid, succinic acid, mandelic acid,fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid,salicylic acid, a pyranosidyl acid, such as glucuronic acid orgalacturonic acid, an alpha hydroxy acid, such as citric acid ortartaric acid, an amino acid, such as aspartic acid or glutamic acid, anaromatic acid, such as benzoic acid or cinnamic acid, a sulfonic acid,such as p-toluenesulfonic acid or ethanesulfonic acid, or the like.

If the compound of the invention is an acid, the desiredpharmaceutically acceptable salt may be prepared by any suitable method,for example, treatment of the free acid with an inorganic or organicbase, such as an amine (primary, secondary or tertiary), an alkali metalhydroxide or alkaline earth metal hydroxide, or the like. Illustrativeexamples of suitable salts include, but are not limited to, organicsalts derived from amino acids, such as glycine and arginine, ammonia,primary, secondary, and tertiary amines, and cyclic amines, such aspiperidine, morpholine and piperazine, and inorganic salts derived fromsodium, calcium, potassium, magnesium, manganese, iron, copper, zinc,aluminum and lithium.

The Formula Ia and Ib compounds of the invention may contain asymmetricor chiral centers, and therefore exist in different stereoisomericforms. It is intended that all stereoisomeric forms of the compounds ofthe invention, including but not limited to, diastereomers, enantiomersand atropisomers, as well as mixtures thereof such as racemic mixtures,form part of the present invention.

In addition, the present invention embraces all geometric and positionalisomers. For example, if a Formula Ia and Ib compound incorporates adouble bond or a fused ring, the cis- and trans-forms, as well asmixtures thereof, are embraced within the scope of the invention. Boththe single positional isomers and mixture of positional isomers are alsowithin the scope of the present invention.

In the structures shown herein, where the stereochemistry of anyparticular chiral atom is not specified, then all stereoisomers arecontemplated and included as the compounds of the invention. Wherestereochemistry is specified by a solid wedge or dashed linerepresenting a particular configuration, then that stereoisomer is sospecified and defined.

The compounds of the present invention may exist in unsolvated as wellas solvated forms with pharmaceutically acceptable solvents such aswater, ethanol, and the like, and it is intended that the inventionembrace both solvated and unsolvated forms.

The compounds of the present invention may also exist in differenttautomeric forms, and all such forms are embraced within the scope ofthe invention. The term “tautomer” or “tautomeric form” refers tostructural isomers of different energies which are interconvertible viaa low energy barrier. For example, proton tautomers (also known asprototropic tautomers) include interconversions via migration of aproton, such as keto-enol and imine-enamine isomerizations. Valencetautomers include interconversions by reorganization of some of thebonding electrons.

The present invention also embraces isotopically-labeled compounds ofthe present invention which are identical to those recited herein, butfor the fact that one or more atoms are replaced by an atom having anatomic mass or mass number different from the atomic mass or mass numberusually found in nature. All isotopes of any particular atom or elementas specified are contemplated within the scope of the compounds of theinvention, and their uses. Exemplary isotopes that can be incorporatedinto compounds of the invention include isotopes of hydrogen, carbon,nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine and iodine,such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ³²P, ³³P, ³⁵S,¹⁸F, ³⁶Cl, ¹²³I and ¹²⁵I. Certain isotopically-labeled compounds of thepresent invention (e.g., those labeled with ³H and ¹⁴C) are useful incompound and/or substrate tissue distribution assays. Tritiated (³H) andcarbon-14 (¹⁴C) isotopes are useful for their ease of preparation anddetectability. Further, substitution with heavier isotopes such asdeuterium (i.e., 2H) may afford certain therapeutic advantages resultingfrom greater metabolic stability (e.g., increased in vivo half-life orreduced dosage requirements) and hence may be preferred in somecircumstances. Positron emitting isotopes such as ¹⁵O, ¹³N, ¹¹C and ¹⁸Fare useful for positron emission tomography (PET) studies to examinesubstrate receptor occupancy. Isotopically labeled compounds of thepresent invention can generally be prepared by following proceduresanalogous to those disclosed in the Schemes and/or in the Examplesherein below, by substituting an isotopically labeled reagent for anon-isotopically labeled reagent.

Preparation of Formula Ia and Ib Compounds

Thienopyrimidine and furanopyrimidine compounds of Formula Ia and Ib maybe synthesized by synthetic routes that include processes analogous tothose well-known in the chemical arts, particularly in light of thedescription contained herein. The starting materials are generallyavailable from commercial sources such as Aldrich Chemicals (Milwaukee,Wis.) or are readily prepared using methods well known to those skilledin the art (e.g., prepared by methods generally described in Louis F.Fieser and Mary Fieser, Reagents for Organic Synthesis, v. 1-19, Wiley,N.Y. (1967-1999 ed.), or Beilsteins Handbuch der organischen Chemie, 4,Aufl. ed. Springer-Verlag, Berlin, including supplements (also availablevia the Beilstein online database).

In certain embodiments, compounds of Formula Ia or Ib may be readilyprepared using procedures well-known to prepare thiophenes, furans,pyrimidines (U.S. Pat. No. 6,608,053; U.S. Pat. No. 6,492,383; U.S. Pat.No. 6,232,320; U.S. Pat. No. 6,187,777; U.S. Pat. No. 3,763,156; U.S.Pat. No. 3,661,908; U.S. Pat. No. 3,475,429; U.S. Pat. No. 5,075,305; US2003/220365; GB 1393161; WO 93/13664;); and other heterocycles, whichare described in: Comprehensive Heterocyclic Chemistry, EditorsKatritzky and Rees, Pergamon Press, 1984.

Compounds of Formula Ia and Ib may be prepared singly or as compoundlibraries comprising at least 2, for example 5 to 1,000 compounds, or 10to 100 compounds. Libraries of compounds of Formula Ia or Ib may beprepared by a combinatorial ‘split and mix’ approach or by multipleparallel syntheses using either solution phase or solid phase chemistry,by procedures known to those skilled in the art. Thus according to afurther aspect of the invention there is provided a compound librarycomprising at least 2 compounds, or pharmaceutically acceptable saltsthereof.

For illustrative purposes, Schemes 1-7 show general methods forpreparing the compounds of the present invention as well as keyintermediates. For a more detailed description of the individualreaction steps, see the Examples section below. Those skilled in the artwill appreciate that other synthetic routes may be used to synthesizethe inventive compounds. Although specific starting materials andreagents are depicted in the Schemes and discussed below, other startingmaterials and reagents can be easily substituted to provide a variety ofderivatives and/or reaction conditions. In addition, many of thecompounds prepared by the methods described below can be furthermodified in light of this disclosure using conventional chemistry wellknown to those skilled in the art.

In preparing compounds of Formulas Ia and Ib, protection of remotefunctionality (e.g., primary or secondary amine) of intermediates may benecessary. The need for such protection will vary depending on thenature of the remote functionality and the conditions of the preparationmethods. Suitable amino-protecting groups include acetyl,trifluoroacetyl, t-butoxycarbonyl (BOC), benzyloxycarbonyl (CBz) and9-fluorenylmethylenoxycarbonyl (Fmoc). The need for such protection isreadily determined by one skilled in the art. For a general descriptionof protecting groups and their use, see T. W. Greene, Protective Groupsin Organic Synthesis, John Wiley & Sons, New York, 1991.

Chim. 5:845.

Methods of Separation

In the methods of preparing the compounds of this invention, it may beadvantageous to separate reaction products from one another and/or fromstarting materials. The desired products of each step or series of stepsis separated and/or purified (hereinafter separated) to the desireddegree of homogeneity by the techniques common in the art. Typicallysuch separations involve multiphase extraction, crystallization from asolvent or solvent mixture, distillation, sublimation, orchromatography. Chromatography can involve any number of methodsincluding, for example: reverse-phase and normal phase; size exclusion;ion exchange; high, medium and low pressure liquid chromatographymethods and apparatus; small scale analytical; simulated moving bed(SMB) and preparative thin or thick layer chromatography, as well astechniques of small scale thin layer and flash chromatography.

Another class of separation methods involves treatment of a mixture witha reagent selected to bind to or render otherwise separable a desiredproduct, unreacted starting material, reaction by product, or the like.Such reagents include adsorbents or absorbents such as activated carbon,molecular sieves, ion exchange media, or the like. Alternatively, thereagents can be acids in the case of a basic material, bases in the caseof an acidic material, binding reagents such as antibodies, bindingproteins, selective chelators such as crown ethers, liquid/liquid ionextraction reagents (LIX), or the like.

Selection of appropriate methods of separation depends on the nature ofthe materials involved. For example, boiling point and molecular weightin distillation and sublimation, presence or absence of polar functionalgroups in chromatography, stability of materials in acidic and basicmedia in multiphase extraction, and the like. One skilled in the artwill apply techniques most likely to achieve the desired separation.

Diastereomeric mixtures can be separated into their individualdiastereomers on the basis of their physical chemical differences bymethods well known to those skilled in the art, such as bychromatography and/or fractional crystallization. Enantiomers can beseparated by converting the enantiomeric mixture into a diastereomericmixture by reaction with an appropriate optically active compound (e.g.,chiral auxiliary such as a chiral alcohol or Mosher's acid chloride),separating the diastereomers and converting (e.g., hydrolyzing) theindividual diastereoisomers to the corresponding pure enantiomers. Also,some of the compounds of the present invention may be atropisomers(e.g., substituted biaryls) and are considered as part of thisinvention. Enantiomers can also be separated by use of a chiral HPLCcolumn.

A single stereoisomer, e.g., an enantiomer, substantially free of itsstereoisomer may be obtained by resolution of the racemic mixture usinga method such as formation of diastereomers using optically activeresolving agents (Eliel, E. and Wilen, S. “Stereochemistry of OrganicCompounds,” John Wiley & Sons, Inc., New York, 1994; Lochmuller, C. H.,(1975) J. Chromatogr., 113(3):283-302). Racemic mixtures of chiralcompounds of the invention can be separated and isolated by any suitablemethod, including: (1) formation of ionic, diastereomeric salts withchiral compounds and separation by fractional crystallization or othermethods, (2) formation of diastereomeric compounds with chiralderivatizing reagents, separation of the diastereomers, and conversionto the pure stereoisomers, and (3) separation of the substantially pureor enriched stereoisomers directly under chiral conditions. See: “DrugStereochemistry, Analytical Methods and Pharmacology,” Irving W. Wainer,Ed., Marcel Dekker, Inc., New York (1993).

Under method (1), diastereomeric salts can be formed by reaction ofenantiomerically pure chiral bases such as brucine, quinine, ephedrine,strychnine, α-methyl-β-phenylethylamine (amphetamine), and the like withasymmetric compounds bearing acidic functionality, such as carboxylicacid and sulfonic acid. The diastereomeric salts may be induced toseparate by fractional crystallization or ionic chromatography. Forseparation of the optical isomers of amino compounds, addition of chiralcarboxylic or sulfonic acids, such as camphorsulfonic acid, tartaricacid, mandelic acid, or lactic acid can result in formation of thediastereomeric salts.

Alternatively, by method (2), the substrate to be resolved is reactedwith one enantiomer of a chiral compound to form a diastereomeric pair(E. and Wilen, S. “Stereochemistry of Organic Compounds”, John Wiley &Sons, Inc., 1994, p. 322). Diastereomeric compounds can be formed byreacting asymmetric compounds with enantiomerically pure chiralderivatizing reagents, such as menthyl derivatives, followed byseparation of the diastereomers and hydrolysis to yield the pure orenriched enantiomer. A method of determining optical purity involvesmaking chiral esters, such as a menthyl ester, e.g., (−) menthylchloroformate in the presence of base, or Mosher ester,α-methoxy-α-(trifluoromethyl)phenyl acetate (Jacob III. J. Org. Chem.,(1982) 47:4165), of the racemic mixture, and analyzing the ¹H NMRspectrum for the presence of the two atropisomeric enantiomers ordiastereomers. Stable diastereomers of atropisomeric compounds can beseparated and isolated by normal- and reverse-phase chromatographyfollowing methods for separation of atropisomeric naphthyl-isoquinolines(WO 96/15111). By method (3), a racemic mixture of two enantiomers canbe separated by chromatography using a chiral stationary phase (“ChiralLiquid Chromatography” (1989) W. J. Lough, Ed., Chapman and Hall, NewYork; Okamoto, J. Chromatogr., (1990) 513:375-378). Enriched or purifiedenantiomers can be distinguished by methods used to distinguish otherchiral molecules with asymmetric carbon atoms, such as optical rotationand circular dichroism.

Biological Evaluation

Determination of the activity of PI3 kinase activity of a compound ofFormula Ia or Ib is possible by a number of direct and indirectdetection methods. Certain exemplary compounds described herein wereprepared, characterized, and assayed for their PI3K binding activity(Examples 364 and 365) and in vitro activity against tumor cells(Example 366). The range of PI3K binding activities was less than 1 nM(nanomolar) to about 10 μM (micromolar). Certain exemplary compounds ofthe invention had PI3K binding activity IC₅₀ values less than 10 nM.Certain compounds of the invention had tumor cell-based activity IC₅₀values less than 100 nM.

The Formula Ia and Ib compounds may inhibit p110 catalytic subunitisoforms including alpha, beta, gamma, and delta as pan inhibitors.Certain Formula Ia and Ib compounds may be p110 isoform selectiveinhibitors by selectively inhibiting one of one of the p110 isoforms;alpha, beta, gamma, or delta. One embodiment of the invention is aFormula Ia or Ib compound which is a p110 alpha selective inhibitor. Ap110 selective inhibitor may mitigate the risk of toxicity due topotential toxicities associated with inhibiting the other p110 isoforms.Certain Formula Ia and Ib compounds may be p110 isoform pan inhibitorsby possessing significant binding to two or more of the p110 isoforms.One embodiment of the invention is a Formula Ia or Ib compound which isa pan inhibitor of PI3K.

Binding of Formula Ia and Ib compounds from Tables 1a and 1b to purifiedpreparations of p110 isoforms alpha, beta, delta, and gamma was measuredby a Scintillation Proximity Assay (SPA) to determine binding activity(IC₅₀ μMol) and selectivity of binding of beta, delta, and gammaisoforms relative to alpha (Example 365). These values are expressed inTable 2.

The cytotoxic or cytostatic activity of Formula Ia and Ib exemplarycompounds was measured by: establishing a proliferating mammalian tumorcell line in a cell culture medium, adding a Formula Ia or Ib compound,culturing the cells for a period from about 6 hours to about 5 days; andmeasuring cell viability (Example 366). Cell-based in vitro assays wereused to measure viability, i.e. proliferation (IC₅₀), cytotoxicity(EC₅₀), and induction of apoptosis (caspase activation).

The in vitro potency of Formula Ia and Ib exemplary compounds wasmeasured by the cell proliferation assay, CellTiter-Glo® LuminescentCell Viability Assay, commercially available from Promega Corp.,Madison, Wis. (Example 366). This homogeneous assay method is based onthe recombinant expression of Coleoptera luciferase (U.S. Pat. No.5,583,024; U.S. Pat. No. 5,674,713; U.S. Pat. No. 5,700,670) anddetermines the number of viable cells in culture based on quantitationof the ATP present, an indicator of metabolically active cells (Crouchet al (1993) J. Immunol. Meth. 160:81-88; U.S. Pat. No. 6,602,677). TheCellTiter-Glo® Assay was conducted in 96 or 384 well format, making itamenable to automated high-throughput screening (HTS) (Cree et al (1995)AntiCancer Drugs 6:398-404). The homogeneous assay procedure involvesadding the single reagent (CellTiter-Glo® Reagent) directly to cellscultured in serum-supplemented medium. Cell washing, removal of mediumand multiple pipetting steps are not required. The system can detect asfew as 15 cells/well in a 384-well format in 10 minutes after addingreagent and mixing.

The homogeneous “add-mix-measure” format results in cell lysis andgeneration of a luminescent signal proportional to the amount of ATPpresent. The amount of ATP is directly proportional to the number ofcells present in culture. The CellTiter-Glo® Assay generates a“glow-type” luminescent signal, produced by the luciferase reaction,which has a half-life generally greater than five hours, depending oncell type and medium used. Viable cells are reflected in relativeluminescence units (RLU). The substrate, Beetle Luciferin, isoxidatively decarboxylated by recombinant firefly luciferase withconcomitant conversion of ATP to AMP and generation of photons. Theextended half-life eliminates the need to use reagent injectors andprovides flexibility for continuous or batch mode processing of multipleplates. This cell proliferation assay can be used with various multiwellformats, e.g. 96 or 384 well format. Data can be recorded by luminometeror CCD camera imaging device. The luminescence output is presented asrelative light units (RLU), measured over time.

The anti-proliferative effects of Formula Ia and Ib exemplary compoundswere measured by the CellTiter-Glob Assay (Example 366) against severaltumor cell lines, including PC3, Detroit 562, and MDAMB361.1. EC₅₀values were established for the tested compounds. The range of in vitrocell potency activities was about 100 nM to about 10 μM.

Certain ADME properties were measured for certain exemplary compounds byassays including: Caco-2 Permeability (Example 367), HepatocyteClearance (Example 368), Cytochrome P450 Inhibition (Example 369),Cytochrome P450 Induction (Example 370), Plasma Protein Binding (Example371), and HERG channel blockage (Example 372).

Pharmaceutical Formulations

In order to use a compound of this invention for the therapeutictreatment (including prophylactic treatment) of mammals includinghumans, it is normally formulated in accordance with standardpharmaceutical practice as a pharmaceutical composition. According tothis aspect of the invention there is provided a pharmaceuticalcomposition comprising a compound of this invention in association witha pharmaceutically acceptable diluent or carrier.

A typical formulation is prepared by mixing a compound of the presentinvention and a carrier, diluent or excipient. Suitable carriers,diluents and excipients are well known to those skilled in the art andinclude materials such as carbohydrates, waxes, water soluble and/orswellable polymers, hydrophilic or hydrophobic materials, gelatin, oils,solvents, water and the like. The particular carrier, diluent orexcipient used will depend upon the means and purpose for which thecompound of the present invention is being applied. Solvents aregenerally selected based on solvents recognized by persons skilled inthe art as safe (GRAS) to be administered to a mammal. In general, safesolvents are non-toxic aqueous solvents such as water and othernon-toxic solvents that are soluble or miscible in water. Suitableaqueous solvents include water, ethanol, propylene glycol, polyethyleneglycols (e.g., PEG 400, PEG 300), etc. and mixtures thereof. Theformulations may also include one or more buffers, stabilizing agents,surfactants, wetting agents, lubricating agents, emulsifiers, suspendingagents, preservatives, antioxidants, opaquing agents, glidants,processing aids, colorants, sweeteners, perfuming agents, flavoringagents and other known additives to provide an elegant presentation ofthe drug (i.e., a compound of the present invention or pharmaceuticalcomposition thereof) or aid in the manufacturing of the pharmaceuticalproduct (i.e., medicament).

The formulations may be prepared using conventional dissolution andmixing procedures. For example, the bulk drug substance (i.e., compoundof the present invention or stabilized form of the compound (e.g.,complex with a cyclodextrin derivative or other known complexationagent) is dissolved in a suitable solvent in the presence of one or moreof the excipients described above. The compound of the present inventionis typically formulated into pharmaceutical dosage forms to provide aneasily controllable dosage of the drug and to enable patient compliancewith the prescribed regimen.

The pharmaceutical composition (or formulation) for application may bepackaged in a variety of ways depending upon the method used foradministering the drug. Generally, an article for distribution includesa container having deposited therein the pharmaceutical formulation inan appropriate form. Suitable containers are well known to those skilledin the art and include materials such as bottles (plastic and glass),sachets, ampoules, plastic bags, metal cylinders, and the like. Thecontainer may also include a tamper-proof assemblage to preventindiscreet access to the contents of the package. In addition, thecontainer has deposited thereon a label that describes the contents ofthe container. The label may also include appropriate warnings.

Pharmaceutical formulations of the compounds of the present inventionmay be prepared for various routes and types of administration. Forexample, a compound of Formula Ia or Ib having the desired degree ofpurity may optionally be mixed with pharmaceutically acceptablediluents, carriers, excipients or stabilizers (Remington'sPharmaceutical Sciences (1980) 16th edition, Osol, A. Ed.), in the formof a lyophilized formulation, milled powder, or an aqueous solution.Formulation may be conducted by mixing at ambient temperature at theappropriate pH, and at the desired degree of purity, withphysiologically acceptable carriers, i.e., carriers that are non-toxicto recipients at the dosages and concentrations employed. The pH of theformulation depends mainly on the particular use and the concentrationof compound, but may range from about 3 to about 8. Formulation in anacetate buffer at pH 5 is a suitable embodiment.

The compound of this invention for use herein is preferably sterile. Inparticular, formulations to be used for in vivo administration must besterile. Such sterilization is readily accomplished by filtrationthrough sterile filtration membranes.

The compound ordinarily can be stored as a solid composition, alyophilized formulation or as an aqueous solution.

The pharmaceutical compositions of the invention will be formulated,dosed and administered in a fashion, i.e., amounts, concentrations,schedules, course, vehicles and route of administration, consistent withgood medical practice. Factors for consideration in this context includethe particular disorder being treated, the particular mammal beingtreated, the clinical condition of the individual patient, the cause ofthe disorder, the site of delivery of the agent, the method ofadministration, the scheduling of administration, and other factorsknown to medical practitioners. The “therapeutically effective amount”of the compound to be administered will be governed by suchconsiderations, and is the minimum amount necessary to prevent,ameliorate, or treat the coagulation factor mediated disorder. Suchamount is preferably below the amount that is toxic to the host orrenders the host significantly more susceptible to bleeding.

As a general proposition, the initial pharmaceutically effective amountof the inhibitor administered parenterally per dose will be in the rangeof about 0.01-100 mg/kg, namely about 0.1 to 20 mg/kg of patient bodyweight per day, with the typical initial range of compound used being0.3 to 15 mg/kg/day.

Acceptable diluents, carriers, excipients and stabilizers are nontoxicto recipients at the dosages and concentrations employed, and includebuffers such as phosphate, citrate and other organic acids; antioxidantsincluding ascorbic acid and methionine; preservatives (such asoctadecyldimethylbenzyl ammonium chloride; hexamethonium chloride;benzalkonium chloride, benzethonium chloride; phenol, butyl or benzylalcohol; alkyl parabens such as methyl or propyl paraben; catechol;resorcinol; cyclohexanol; 3-pentanol; and m-cresol); low molecularweight (less than about 10 residues) polypeptides; proteins, such asserum albumin, gelatin, or immunoglobulins; hydrophilic polymers such aspolyvinylpyrrolidone; amino acids such as glycine, glutamine,asparagine, histidine, arginine, or lysine; monosaccharides,disaccharides and other carbohydrates including glucose, mannose, ordextrins; chelating agents such as EDTA; sugars such as sucrose,mannitol, trehalose or sorbitol; salt-forming counter-ions such assodium; metal complexes (e.g., Zn-protein complexes); and/or non-ionicsurfactants such as TWEEN™, PLURONICS™ or polyethylene glycol (PEG). Theactive pharmaceutical ingredients may also be entrapped in microcapsulesprepared, for example, by coacervation techniques or by interfacialpolymerization, for example, hydroxymethylcellulose orgelatin-microcapsules and poly-(methylmethacylate) microcapsules,respectively, in colloidal drug delivery systems (for example,liposomes, albumin microspheres, microemulsions, nano-particles andnanocapsules) or in macroemulsions. Such techniques are disclosed inRemington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980).

Sustained-release preparations of compounds of Formula Ia and Ib may beprepared. Suitable examples of sustained-release preparations includesemipermeable matrices of solid hydrophobic polymers containing acompound of Formula Ia or Ib, which matrices are in the form of shapedarticles, e.g., films, or microcapsules. Examples of sustained-releasematrices include polyesters, hydrogels (for example,poly(2-hydroxyethyl-methacrylate), or poly(vinyl alcohol)), polylactides(U.S. Pat. No. 3,773,919), copolymers of L-glutamic acid andgamma-ethyl-L-glutamate, non-degradable ethylene-vinyl acetate,degradable lactic acid-glycolic acid copolymers such as the LUPRONDEPOT™ (injectable microspheres composed of lactic acid-glycolic acidcopolymer and leuprolide acetate) and poly-D-(−)-3-hydroxybutyric acid.

The formulations include those suitable for the administration routesdetailed herein. The formulations may conveniently be presented in unitdosage form, and may be prepared by any of the methods well known in theart of pharmacy. Techniques and formulations generally are found inRemington's Pharmaceutical Sciences (Mack Publishing Co., Easton, Pa.).Such methods include the step of bringing into association the activeingredient with the carrier which constitutes one or more accessoryingredients. In general the formulations are prepared by uniformly andintimately bringing into association the active ingredient with liquidcarriers or finely divided solid carriers or both, and then, ifnecessary, shaping the product.

Formulations of a compound of Formula Ia or Ib suitable for oraladministration may be prepared as discrete units such as pills,capsules, cachets or tablets each containing a predetermined amount of acompound of Formula Ia or Ib.

Compressed tablets may be prepared by compressing in a suitable machinethe active ingredient in a free-flowing form such as a powder orgranules, optionally mixed with a binder, lubricant, inert diluent,preservative, surface active or dispersing agent. Molded tablets may bemade by molding in a suitable machine a mixture of the powdered activeingredient moistened with an inert liquid diluent. The tablets mayoptionally be coated or scored and optionally are formulated so as toprovide slow or controlled release of the active ingredient therefrom.

Tablets, troches, lozenges, aqueous or oil suspensions, dispersiblepowders or granules, emulsions, hard or soft capsules, e.g., gelatincapsules, syrups or elixirs may be prepared for oral use. Formulationsof compounds of Formula Ia or Ib intended for oral use may be preparedaccording to any method known to the art for the manufacture ofpharmaceutical compositions and such compositions may contain one ormore agents including sweetening agents, flavoring agents, coloringagents and preserving agents, in order to provide a palatablepreparation. Tablets containing the active ingredient in admixture withnon-toxic pharmaceutically acceptable excipient which are suitable formanufacture of tablets are acceptable. These excipients may be, forexample, inert diluents, such as calcium or sodium carbonate, lactose,calcium or sodium phosphate; granulating and disintegrating agents, suchas maize starch, or alginic acid; binding agents, such as starch,gelatin or acacia; and lubricating agents, such as magnesium stearate,stearic acid or talc. Tablets may be uncoated or may be coated by knowntechniques including microencapsulation to delay disintegration andadsorption in the gastrointestinal tract and thereby provide a sustainedaction over a longer period. For example, a time delay material such asglyceryl monostearate or glyceryl distearate alone or with a wax may beemployed.

For treatment of the eye or other external tissues, e.g., mouth andskin, the formulations are preferably applied as a topical ointment orcream containing the active ingredient(s) in an amount of, for example,0.075 to 20% w/w. When formulated in an ointment, the active ingredientsmay be employed with either a paraffinic or a water-miscible ointmentbase. Alternatively, the active ingredients may be formulated in a creamwith an oil-in-water cream base.

If desired, the aqueous phase of the cream base may include a polyhydricalcohol, i.e., an alcohol having two or more hydroxyl groups such aspropylene glycol, butane 1,3-diol, mannitol, sorbitol, glycerol andpolyethylene glycol (including PEG 400) and mixtures thereof. Thetopical formulations may desirably include a compound which enhancesabsorption or penetration of the active ingredient through the skin orother affected areas. Examples of such dermal penetration enhancersinclude dimethyl sulfoxide and related analogs.

The oily phase of the emulsions of this invention may be constitutedfrom known ingredients in a known manner. While the phase may comprisemerely an emulsifier, it desirably comprises a mixture of at least oneemulsifier with a fat or an oil or with both a fat and an oil.Preferably, a hydrophilic emulsifier is included together with alipophilic emulsifier which acts as a stabilizer. It is also preferredto include both an oil and a fat. Together, the emulsifier(s) with orwithout stabilizer(s) make up the so-called emulsifying wax, and the waxtogether with the oil and fat make up the so-called emulsifying ointmentbase which forms the oily dispersed phase of the cream formulations.Emulsifiers and emulsion stabilizers suitable for use in the formulationof the invention include Tween® 60, Span® 80, cetostearyl alcohol,benzyl alcohol, myristyl alcohol, glyceryl mono-stearate and sodiumlauryl sulfate.

Aqueous suspensions of Formula Ia or Ib compounds contain the activematerials in admixture with excipients suitable for the manufacture ofaqueous suspensions. Such excipients include a suspending agent, such assodium carboxymethylcellulose, croscarmellose, povidone,methylcellulose, hydroxypropyl methylcellulose, sodium alginate,polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing orwetting agents such as a naturally occurring phosphatide (e.g.,lecithin), a condensation product of an alkylene oxide with a fatty acid(e.g., polyoxyethylene stearate), a condensation product of ethyleneoxide with a long chain aliphatic alcohol (e.g.,heptadecaethyleneoxycetanol), a condensation product of ethylene oxidewith a partial ester derived from a fatty acid and a hexitol anhydride(e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension mayalso contain one or more preservatives such as ethyl or n-propylp-hydroxybenzoate, one or more coloring agents, one or more flavoringagents and one or more sweetening agents, such as sucrose or saccharin.

The pharmaceutical compositions of compounds of Formula Ia or Ib may bein the form of a sterile injectable preparation, such as a sterileinjectable aqueous or oleaginous suspension. This suspension may beformulated according to the known art using those suitable dispersing orwetting agents and suspending agents which have been mentioned above.The sterile injectable preparation may also be a sterile injectablesolution or suspension in a non-toxic parenterally acceptable diluent orsolvent, such as a solution in 1,3-butanediol or prepared as alyophilized powder. Among the acceptable vehicles and solvents that maybe employed are water, Ringer's solution and isotonic sodium chloridesolution. In addition, sterile fixed oils may conventionally be employedas a solvent or suspending medium. For this purpose any bland fixed oilmay be employed including synthetic mono- or diglycerides. In addition,fatty acids such as oleic acid may likewise be used in the preparationof injectables.

The amount of active ingredient that may be combined with the carriermaterial to produce a single dosage form will vary depending upon thehost treated and the particular mode of administration. For example, atime-release formulation intended for oral administration to humans maycontain approximately 1 to 1000 mg of active material compounded with anappropriate and convenient amount of carrier material which may varyfrom about 5 to about 95% of the total compositions (weight:weight). Thepharmaceutical composition can be prepared to provide easily measurableamounts for administration. For example, an aqueous solution intendedfor intravenous infusion may contain from about 3 to 500 μg of theactive ingredient per milliliter of solution in order that infusion of asuitable volume at a rate of about 30 mL/hr can occur.

Formulations suitable for parenteral administration include aqueous andnon-aqueous sterile injection solutions which may contain anti-oxidants,buffers, bacteriostats and solutes which render the formulation isotonicwith the blood of the intended recipient; and aqueous and non-aqueoussterile suspensions which may include suspending agents and thickeningagents.

Formulations suitable for topical administration to the eye also includeeye drops wherein the active ingredient is dissolved or suspended in asuitable carrier, especially an aqueous solvent for the activeingredient. The active ingredient is preferably present in suchformulations in a concentration of about 0.5 to 20% w/w, for exampleabout 0.5 to 10% w/w, for example about 1.5% w/w.

Formulations suitable for topical administration in the mouth includelozenges comprising the active ingredient in a flavored basis, usuallysucrose and acacia or tragacanth; pastilles comprising the activeingredient in an inert basis such as gelatin and glycerin, or sucroseand acacia; and mouthwashes comprising the active ingredient in asuitable liquid carrier.

Formulations for rectal administration may be presented as a suppositorywith a suitable base comprising for example cocoa butter or asalicylate.

Formulations suitable for intrapulmonary or nasal administration have aparticle size for example in the range of 0.1 to 500 microns (includingparticle sizes in a range between 0.1 and 500 microns in incrementsmicrons such as 0.5, 1, 30 microns, 35 microns, etc.), which isadministered by rapid inhalation through the nasal passage or byinhalation through the mouth so as to reach the alveolar sacs. Suitableformulations include aqueous or oily solutions of the active ingredient.Formulations suitable for aerosol or dry powder administration may beprepared according to conventional methods and may be delivered withother therapeutic agents such as compounds heretofore used in thetreatment or prophylaxis disorders as described below.

Formulations suitable for vaginal administration may be presented aspessaries, tampons, creams, gels, pastes, foams or spray formulationscontaining in addition to the active ingredient such carriers as areknown in the art to be appropriate.

The formulations may be packaged in unit-dose or multi-dose containers,for example sealed ampoules and vials, and may be stored in afreeze-dried (lyophilized) condition requiring only the addition of thesterile liquid carrier, for example water, for injection immediatelyprior to use. Extemporaneous injection solutions and suspensions areprepared from sterile powders, granules and tablets of the kindpreviously described. Preferred unit dosage formulations are thosecontaining a daily dose or unit daily sub-dose, as herein above recited,or an appropriate fraction thereof, of the active ingredient.

The invention further provides veterinary compositions comprising atleast one active ingredient as above defined together with a veterinarycarrier therefore. Veterinary carriers are materials useful for thepurpose of administering the composition and may be solid, liquid orgaseous materials which are otherwise inert or acceptable in theveterinary art and are compatible with the active ingredient. Theseveterinary compositions may be administered parenterally, orally or byany other desired route.

Combination Therapy

The compounds of Formulas Ia and Ib may be employed alone or incombination with other therapeutic agents for the treatment of a diseaseor disorder described herein, such as a hyperproliferative disorder(e.g., cancer). In certain embodiments, a compound of Formula Ia or Ibis combined in a pharmaceutical combination formulation, or dosingregimen as combination therapy, with a second compound that hasanti-hyperproliferative properties or that is useful for treating ahyperproliferative disorder (e.g., cancer). The second compound of thepharmaceutical combination formulation or dosing regimen preferably hascomplementary activities to the compound of Formula Ia or Ib such thatthey do not adversely affect each other. Such compounds are suitablypresent in combination in amounts that are effective for the purposeintended. In one embodiment, a composition of this invention comprises acompound of Formula Ia or Ib, or a stereoisomer, geometric isomer,tautomer, solvate, metabolite, or pharmaceutically acceptable salt orprodrug thereof, in combination with a chemotherapeutic agent such asdescribed herein.

The combination therapy may be administered as a simultaneous orsequential regimen. When administered sequentially, the combination maybe administered in two or more administrations. The combinedadministration includes coadministration, using separate formulations ora single pharmaceutical formulation, and consecutive administration ineither order, wherein preferably there is a time period while both (orall) active agents simultaneously exert their biological activities.

Suitable dosages for any of the above coadministered agents are thosepresently used and may be lowered due to the combined action (synergy)of the newly identified agent and other chemotherapeutic agents ortreatments.

The combination therapy may provide “synergy” and prove “synergistic”,i.e., the effect achieved when the active ingredients used together isgreater than the sum of the effects that results from using thecompounds separately. A synergistic effect may be attained when theactive ingredients are: (1) co-formulated and administered or deliveredsimultaneously in a combined, unit dosage formulation; (2) delivered byalternation or in parallel as separate formulations; or (3) by someother regimen. When delivered in alternation therapy, a synergisticeffect may be attained when the compounds are administered or deliveredsequentially, e.g., by different injections in separate syringes. Ingeneral, during alternation therapy, an effective dosage of each activeingredient is administered sequentially, i.e., serially, whereas incombination therapy, effective dosages of two or more active ingredientsare administered together.

In a particular embodiment of anti-cancer therapy, a compound of FormulaIa or Ib, or a stereoisomer, geometric isomer, tautomer, solvate,metabolite, or pharmaceutically acceptable salt or prodrug thereof, maybe combined with other chemotherapeutic, hormonal or antibody agentssuch as those described herein, as well as combined with surgicaltherapy and radiotherapy. Combination therapies according to the presentinvention thus comprise the administration of at least one compound ofFormula Ia or Ib, or a stereoisomer, geometric isomer, tautomer,solvate, metabolite, or pharmaceutically acceptable salt or prodrugthereof, and the use of at least one other cancer treatment method. Theamounts of the compound(s) of Formula Ia or Ib and the otherpharmaceutically active chemotherapeutic agent(s) and the relativetimings of administration will be selected in order to achieve thedesired combined therapeutic effect.

Metabolites of Compounds of Formulas Ia and Ib

Also falling within the scope of this invention are the in vivometabolic products of Formulas Ia and Ib described herein. Such productsmay result for example from the oxidation, reduction, hydrolysis,amidation, deamidation, esterification, deesterification, enzymaticcleavage, and the like, of the administered compound. Accordingly, theinvention includes metabolites of compounds of Formulas Ia and Ib,including compounds produced by a process comprising contacting acompound of this invention with a mammal for a period of time sufficientto yield a metabolic product thereof.

Metabolite products typically are identified by preparing aradiolabelled (e.g., ¹⁴C or ³H) isotope of a compound of the invention,administering it parenterally in a detectable dose (e.g., greater thanabout 0.5 mg/kg) to an animal such as rat, mouse, guinea pig, monkey, orto man, allowing sufficient time for metabolism to occur (typicallyabout 30 seconds to 30 hours) and isolating its conversion products fromthe urine, blood or other biological samples. These products are easilyisolated since they are labeled (others are isolated by the use ofantibodies capable of binding epitopes surviving in the metabolite). Themetabolite structures are determined in conventional fashion, e.g., byMS, LC/MS or NMR analysis. In general, analysis of metabolites is donein the same way as conventional drug metabolism studies well known tothose skilled in the art. The metabolite products, so long as they arenot otherwise found in vivo, are useful in diagnostic assays fortherapeutic dosing of the compounds of the invention.

Prodrugs of Formula Ia and Ib Compounds

In addition to compounds of Formulas Ia and Ib, the invention alsoincludes pharmaceutically acceptable prodrugs of such compounds.Prodrugs include compounds wherein an amino acid residue, or apolypeptide chain of two or more (e.g., two, three or four) amino acidresidues, is covalently joined through an amide or ester bond to a freeamino, hydroxy or carboxylic acid group of a compound of the presentinvention. The amino acid residues include but are not limited to the 20naturally occurring amino acids commonly designated by three lettersymbols and also includes phosphoserine, phosphothreonine,phosphotyrosine, 4-hydroxyproline, hydroxylysine, demosine, isodemosine,gamma-carboxyglutamate, hippuric acid, octahydroindole-2-carboxylicacid, statine, 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid,penicillamine, ornithine, 3-methylhistidine, norvaline, beta-alanine,gamma-aminobutyric acid, citrulline, homocysteine, homoserine,methyl-alanine, para-benzoylphenylalanine, phenylglycine,propargylglycine, sarcosine, methionine sulfone and tert-butylglycine.

Additional types of prodrugs are also encompassed. For instance, a freecarboxyl group of a compound of Formula Ia or Ib can be derivatized asan amide or alkyl ester. As another example, compounds of this inventioncomprising free hydroxy groups may be derivatized as prodrugs byconverting the hydroxy group into a group such as, but not limited to, aphosphate ester, hemisuccinate, dimethylaminoacetate, orphosphoryloxymethyloxycarbonyl group, as outlined in Advanced DrugDelivery Reviews, (1996) 19:115. Carbamate prodrugs of hydroxy and aminogroups are also included, as are carbonate prodrugs, sulfonate estersand sulfate esters of hydroxy groups. Derivatization of hydroxy groupsas (acyloxy)methyl and (acyloxy)ethyl ethers, wherein the acyl group maybe an alkyl ester optionally substituted with groups including, but notlimited to, ether, amine and carboxylic acid functionalities, or wherethe acyl group is an amino acid ester as described above, are alsoencompassed. Prodrugs of this type are described in J. Med. Chem.,(1996), 39:10. More specific examples include replacement of thehydrogen atom of the alcohol group with a group such as(C₁-C₆)alkanoyloxymethyl, 1-((C₁-C₆)alkanoyloxy)ethyl,1-methyl-1-((C₁-C₆)alkanoyloxy)ethyl, (C₁-C₆)alkoxycarbonyloxymethyl,N—(C₁-C₆)alkoxycarbonylaminomethyl, succinoyl, (C₁-C₆)alkanoyl,α-amino(C₁-C₄)alkanoyl, arylacyl and (X-aminoacyl, orα-aminoacyl-α-aminoacyl, where each α-aminoacyl group is independentlyselected from the naturally occurring L-amino acids, P(O)(OH)₂,—P(O)(O(C₁-C₆)alkyl)₂ or glycosyl (the radical resulting from theremoval of a hydroxyl group of the hemiacetal form of a carbohydrate).

Free amine groups of compounds of Formulas Ia and Ib can also bederivatized as amides, sulfonamides or phosphonamides. All of thesemoieties may incorporate groups including, but not limited to, ether,amine and carboxylic acid functionalities. For example, a prodrug can beformed by the replacement of a hydrogen atom in the amine group with agroup such as R-carbonyl, RO-carbonyl, NRR′-carbonyl, wherein R and R′are each independently (C₁-C₁₀)alkyl, (C₃-C₇)cycloalkyl, or benzyl, orR-carbonyl is a natural α-aminoacyl or natural α-aminoacyl-naturalα-aminoacyl, —C(OH)C(O)OY wherein Y is H, (C₁-C₆)alkyl or benzyl,—C(OY₀)Y₁ wherein Y₀ is (C₁-C₄) alkyl and Y₁ is (C₁-C₆)alkyl,carboxy(C₁-C₆)alkyl, amino(C₁-C₄)alkyl or mono-N— ordi-N,N—(C₁-C₆)alkylaminoalkyl, or —C(Y₂)Y₃ wherein Y₂ is H or methyl andY₃ is mono-N— or di-N,N—(C₁-C₆)alkylamino, morpholino, piperidin-1-yl orpyrrolidin-1-yl.

General Preparative Procedures

The Suzuki-type coupling reaction is useful to attach a fused bicyclicheterocycle or fused bicyclic heteroaryl at the 2-position of thepyrimidine ring (see Scheme 4). Generally, substituted2-chloro-4-morpholinothieno[3,2-d]pyrimidine 5 or2-chloro-4-morpholinothieno[2,3-d]pyrimidine 6 may be combined with 1.5equivalents of4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)1H-indazole 7, anddissolved in 3 equivalents of sodium carbonate as a 1 molar solution inwater and an equal volume of acetonitrile. A catalytic amount, or more,of a low valent palladium reagent, such asbis(triphenylphosphine)palladium(II) dichloride, is added. A variety ofboronic acids or boronic esters can be used in place of the indazoleboronic ester indicated. Also alternatively, the nitrogen of theindazole may be protected, for example with a tetrahydropyranyl group;see compound 40. In some cases potassium acetate was used in place ofsodium carbonate to adjust the pH of the aqueous layer. The reaction wasthen heated to about 140-150° C. under pressure in a Biotage Optimizermicrowave reactor (Biotage, Inc.) for 10 to 30 minutes. The contents areextracted with ethyl acetate, or another organic solvent. Afterevaporation of the organic layer the product, 8 or 9, may be purified onsilica or by reverse phase HPLC.

Caco-2 cells were seeded onto Millipore Multiscreen plates at 1×10⁵cells/cm², and were cultured for 20 days. Assessment of compoundpermeability was subsequently conducted. The compounds were applied tothe apical surface (A) of cell monolayers and compound permeation intothe basolateral (B) compartment was measured. This was performed in thereverse direction (B−A) to investigate active transport. A permeabilitycoefficient value, P_(app), for each compound, a measure of the rate ofpermeation of the compound across the membrane, was calculated.Compounds were grouped into low (P_(app)</=1.0×10⁶ cm/s) or high(P_(app)>/=1.0×10⁶ cm/s) absorption potential based on comparison withcontrol compounds with established human absorption.

For assessment of a compound's ability to undergo active efflux, theratio of basolateral (B) to apical (A) transport compared with A to Bwas determined. Values of B−A/A−B>/=1.0 indicated the occurrence ofactive cellular efflux. The had P_(app) values>/=1.0×10⁶ cm/s.

Example 368 Hepatocyte Clearance

Suspensions of cryopreserved human hepatocytes were used. Incubationswere performed at compound concentration of 1 mM or 3 μM at a celldensity of 0.5×10⁶ viable cells/mL. The final DMSO concentration in theincubation was 0.25%. Control incubations were also performed in theabsence of cells to reveal any non-enzymatic degradation. Duplicatesamples (50 μL) were removed from the incubation mixture at 0, 5, 10,20, 40 and 60 minutes (control sample at 60 minutes only) and added tomethanol-containing internal standard (100 μL)—to terminate thereaction. Tolbutamide, 7-hydroxycoumarin, and testosterone were used ascontrol compounds. Samples were centrifuged and the supernatants at eachtime point pooled for analysis by LC-MSMS. From a plot of ln peak arearatio (parent compound peak area/internal standard peak area) againsttime, intrinsic clearance (CL_(int)) was calculated as follows: CL_(int)(μl/min/million cells)=V×k, where k is the elimination rate constant,obtained from the gradient of ln concentration plotted against time; Vis a volume term derived from the incubation volume and is expressed asuL 10⁶ cells⁻¹.

Compounds from Tables 1a and 1b were characterized on the basis of low(CL</=4.6 μL/min/10⁶ cells), medium (CL>/=4.6; </=25.2 μl/min/10⁶ cells)and high (>/=25.2 μl/min/10⁶ cells) hepatocyte clearance.

Probe substrates for CYP3A4 and CYP1A2 were addedfor 30 minutes and 1 h before the end of the incubation. At 72 h, cellsand media were removed and the extent of metabolism of each probesubstrate quantified by LC-MS/MS. The experiment was controlled by usinginducers of the individual P450s incubated at one concentration intriplicate to determine the extent of induction of cytochrome P450enzymes.

Example 371 Plasma Protein Binding

Solutions of test compound (5 um, 0.5% final DMSO concentration) wereprepared in buffer and 10% plasma (v/v in buffer). A 96 well HT dialysisplate was assembled so that each well was divided in two by asemi-permeable cellulose membrane. The buffer solution was added to oneside of the membrane and the plasma solution to the other side;incubations were then conducted at 37° C. over 2 h in triplicate. Thecells were subsequently emptied, and the solutions for each batch ofcompounds were combined into two groups (plasma-free andplasma-containing) then analysed by LC-MSMS using two sets ofcalibration standards for plasma-free (6 points) and plasma-containingsolutions (7 points). The fraction unbound value for the compounds ofTables 1a and 1b was calculated as: highly protein bound compounds(>/=90% bound) had an Fu</=0.1.

Example 372 HERG Channel Blockage

The compounds of Tables 1a and 1b were evaluated for modulation ofrubidium efflux from HEK-294 cells stably expressing HERG potassiumchannels using established flux methodology. Cells were prepared inmedium containing RbCl and were plated into 96-well plates and grownovernight to form monolayers. The efflux experiment was initiated byaspirating the media and washing each well with 3×100 μL ofpre-incubation buffer (containing low [K⁺]) at room temperature.Following the final aspiration, 50 μL of working stock (2×) compound wasadded to each well and incubated at room temperature for 10 minutes. 50μL of stimulation buffer (containing high [K⁺]) was then added to eachwell giving the final test compound concentrations. Cell plates werethen incubated at room temperature for a further 10 minutes. 80 μL ofsupernatant from each well was then transferred to equivalent wells of a96-well plate and analysed via atomic emission spectroscopy. Thecompound was screened as 10pt duplicate IC₅₀ curves, n=2, from a topconcentration of 100 μM.
